     Define notional functional and non-functional Behavior
    </a>
   </em>
   <p>
    <p>
     This task is similar to System Need Analysis 'Define notional functional and non-functional Behavior'.
    </p>
    <p>
     Define a functional behaviour that should fulfil former functional analysis, addressing:
    </p>
    <ul>
     <li>
      design &amp; description of solution behaviour instead of need expression
     </li>
     <li>
      first design decisions reagrding behaviour
     </li>
    </ul>
    <p>
     Build and maintain justification and traceability links with System Need Analysis functions, functional chains, scenarios, modes &amp;states, data etc.
    </p>
    <p>
     More precisely,
    </p>
    <ul>
     <li>
      Identify functions required to satisfy and implement all system need analysis functions
     </li>
     <li>
      Complement them with necessary functions that were not identified in need analysis
     </li>
     <li>
      List and detail information, data flows, managed, exchanged and required by all these functions (internal or external to system); including required standards &amp; interfaces
     </li>
     <li>
      Identify functional chains traversing the system/SW in order to implement&nbsp;need defined&nbsp;functional chains&nbsp;(traversing functions &amp; data flows); similarly define functional scenarios implementing those defined at need level;
      <br/>
      enrich them if needed in order to appropriately define and check solution behaviour
     </li>
     <li>
      Identify system/SW modes &amp; states, relate them to functions; enrich them if needed
     </li>
     <li>
      Create and maintain traceability links with system need analysis (e.g. between functions, between functional chains, between scenarios).
     </li>
    </ul>
    <p>
     &nbsp;
    </p>
    <p>
     Identify all major dimensioning needs, and [non-functional] constraints, relating them to the appropriate fonctions, functional chains, actors&hellip; and associated scenarios, and relate them to system scenarios: e.g.
    </p>
    <ul>
     <li>
      Identify non-functional constraints (performance, safety&hellip;) and relate them to concerned functions, functional chains&hellip;
     </li>
     <li>
      Identify industrial constraints not coming from customer/user: ability to produce, to test, to maintain, to sub-contract&hellip;
     </li>
     <li>
      When intending to reuse existing assets, check this functional/non-functional analysis against these assets for compatibility.
     </li>
     <li>
      Enrich system scenarios with non-functional &amp; industrial constraints
     </li>
     <li>
      Identify and select main (non functional) viewpoints (concerns) (*) susceptible to impact the functional analysis.
      <br/>
      Each viewpoint should emphasise a specific set of constraints or expected behaviour, quality, respect of non-functional properties&hellip; At least one viewpoint should be dedicated to Reuse and Product Policy.
     </li>
     <li>
      Try to order them in terms of importance, relative priority.
     </li>
    </ul>
    <p>
     &nbsp;
    </p>
    <p>
     Ensure traceability/justification links between system need and notional and functional/non-functional analyses, and check consistency/coherency between them.
    </p>
